Driven by an older generation that is trying to hold on to something that has passed. Will only lead to more unrest as it isn't a simple thing. Half of Scotland already wanted to become independent of England before and now that they will be staying in the union that will only get stronger.
Ireland is going to have to address the separation of the country again too. Hope this time it remains peaceful.
he English Empire stood for 1000 yrs b4 the EU, it will be ok on its own, it will have a few bumps and bruises along the way but they will be ok, hopefully the bruises go to their politicians
